It is possible that the backplane lamps and lamp supply has failed. It is also possible that there is a failure in the power supply or on one of the circuit boards. Without doing some tests it is impossible to accurately determine the areas of fault.

I have the same problem. rca 26lb30rqd. The red light is on (steady), and when I hit the power button, the blue light comes on for a second, then goes black, w/ no display. Before this happened, the display was extremely bright with ghosting. The picture was un-viewable. Did you every figure out the problem?

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

hi,
the most probably is broken one of neon lamps that illuminates led display .you can check that when you turn it on and flashes, see if one side of screen is brighter then other.
also,it can be that power supply in led display got weakened and haven`t got enough power,but that is job for service like any bigger failure.
this is not the only answer,there is always several solutions but you have to give more informations about malfunctions.
good luck!

Sorry to inform you my freind, but the main board has to be replaced in this beast. Could get expensive. there are no schematics and or componets listed to repair this module. Its a board level repair only. Try going to ptscorp.com, find their phone number, and see if they repair these boards. if not you will need to contact the manufacturer for replacement boards. good Luck
